I love this app. I used it for my previous pregnancy back in 2017 and have been using it throughout my current pregnancy so far. However for the past couple of days, in any group I am a part of the threads have been arranged from oldest to newest and there is no way to change it. If it doesn't get fixed shortly I am going to have to resort to finding a new pregnancy app/tracker to use which will be a huge disappointment.

Love this app but only thing stopping it from getting 5*, is when putting in the feeds for a bottle you have to put the breast milk and formula in separately rather then putting them in together when they are for the same feed/ bottle instead you have to waste time putting it in separately. If this could be fixed maybe a similar screen to the pump screen with the ml options on both sides, instead of L& R you could pick the different milk options if using more then one.

Won't show images in the app. When it works, it's decent. The weekly videos are a bit cringey (I'm from the UK and you can tell this app was developed for American mums to be). The best bit is seeing what the baby may look like week by week, how big it is and it's developmental milestones but like I said, the images have stopped showing. In turn this has stopped the information showing because you can't click on the images.
